BOTTLE-STOPPER.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed November 1, 1905. Serial No. 285,445.

To all whom "it may concern:

Be it known that we, PAUL H. A. LEDER, a subject of the German Emperor,residing at Baltimore, State of Maryland, and BERNARD F. ScHUBER'r, acitizen of the United States, residing at Washington, District ofColumbia, have invented certain new and useful Improvements inBottle-Stoppers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

Our invention relates particularly to that class of bottle stoppers usedon bottles for beverages and the like, such bottles not being sold butare returned to the dealer and refilled. On such bottles the stoppersare usually permanently secured to the bottle neck by means of the wellknown wire bail, and in many stoppers of this class the sealing mediumreadily becomes detached from the stopper cap and is lost; or where thesealing medium is permanently secured to the bail the entire device hasto be replaced when the sealing medium becomes worn.

The object of this invention is to obviate these defects by guardingagainst such loss and at the same time permit of ready removal of thesealing medium when necessary without removing the bail from the bottle.

The invention consists in providing a casing capable of holding asealing medium made up of several independent disks which we prel'er touse, such disks being of different materials, one of which is made verythin of some material unaffected by acids, such as mica and the like andwhich comes in contact with the contents of the bottle, and other disksresting on the former and upon which the pressure is brought either bythe cap or by the bail itself resting directly on the top disk.

In the drawings, Figure 1 is an elevation of a bottle stopper, wherein,for the purpose of illustration, the stopper is shown secured to abottle neck and showing one means of securing the casing together. Fig.2 shows in perspective the several parts of the stopper before beingassembled. Fig. 3 is a vertical section of a modified form, showing thecap screwed onto the easing.

A designates a bottle neck having a well known form of bail or clampingmember B secured thereto in any known manner. The fastening means hereshown for securing the bail consists of a wire I) wound around thebottle neck behind a flange a formed thereon.

The stopper comprises a metallic retaining ring O having an internalflange 0 formed on its lower edge forming an opening 0 of greaterdiameter than the mouth of the bottle. In this ring is mounted a thindisk D, which, when the stopper is not pressed down on the bottle, isretained therein by the internal flange c. This disk is preferably madeof mica so that if the bottle or jar contains acids of any kind the diskwill not be affected thereby. But any well known substitute may be used,such as parafiined paper or the like. Resting on the disk D is a seconddisk E preferably composed of a flexible material such as felt, leather,cork or rubber for the purpose of making the mica disk conform to themouth of the bottle and on the latter disk is placed preferably a woodenplug F having a transverse groove f formed in its top.

The disks are held in place in the ring 0 by means of an inclosing cap Gwhich fits down over the ring. The cap is secured to the bail by meansof a crimp g in the top of cap, said crimp embracing the bail and lyingin the groove f of the wooden plug F. The friction between the cover andring will under 'ordinary circumstances hold the two parts together, butto insure against accidental separation and loss they may be se curedtogether by pins 01' small screws g passing through the two thicknessesand if desired into the Wooden plug F. As shown in Fig. 3 both the capand ring are provided with screw threads g and 0 respectively forholding the two parts together. The ring in this instance has notches 0formed therein for the reception of a tool or spanner to aid inunscrewing the two parts.

We do not wish to be limited to the exact number and kind of disks abovedescribed for making up the sealing medium for instead of several disksof different materials, one of any preferred material may besubstituted, the aim of the invention being to provide a cap that may beeasily taken apart and readily reassembled for the purpose ofsubstituting a new sealing medium when it becomes necessary.

We claim:

1. In combination with a bottle neck, a ring having an internal flangeforming an opening of larger diameterthan the mouth of the bottle, agrooved sealing member seated in the ring, a cap to receive the ringhaving a groove taking into the groove of the sealing member, and a bailmounted in the groove of the cap.

2. In combination with a bottle neck, a ring having an internal flangeforming an opening of larger diameter than the month of the bottle, aflexible sealing member seated on said flange, :1 g'l'OOWZG rigid memberseated on the flexible member, a cap to receive the ring having a groovetaking into the groove of the rigid member and a 5 bail mounted in thegroove 01 the cap.

In combination with a bottle neck, a screW-threzulecl ring hzwing' aninternal flange forming an opening of larger diameter than the mouth ofthe bottle, a flexible sealing member seated on said flange, a groovedrig-id 10 member seated on said flexible member, a screw-threaded
